Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Will Deacon:
"Once again, Catalin's off on holiday and I'm looking after the arm64
tree. Please can you pull the following arm64 updates for 3.17?
Note that this branch also includes the new GICv3 driver (merged via a
stable tag from Jason's irqchip tree), since there is a fix for older
binutils on top.
Changes include:
- context tracking support (NO_HZ_FULL) which narrowly missed 3.16
- vDSO layout rework following Andy's work on x86
- TEXT_OFFSET fuzzing for bootloader testing
- /proc/cpuinfo tidy-up
- preliminary work to support 48-bit virtual addresses, but this is
currently disabled until KVM has been ported to use it (the patches
do, however, bring some nice clean-up)
- boot-time CPU sanity checks (especially useful on heterogenous
systems)
- support for syscall auditing
- support for CC_STACKPROTECTOR
- defconfig updates"
